Hard to know what to say really, some are riddled with malware
at first I thought this was going to cover that many medical devices ran older exploitable windows (I've encountered devices with winCE and NT4 built into them, and servers that we were told "don't run windows updates on as they'll break the application)
As more a more med devices are connected to the web exploits will jump to those devices, and could really cause havoc
They really need to investigate this more, and I wonder if anyone has died from it.
The irony..Viruses found in hospital...
